it's a lot of they, but it gonna be awesome for blockland, i guess...
-new clothes
-new default cars (taxis, police car, bus, truck)
-new animations (walking animation for example, same as run animation, but is more slower, and the dance animation)
-possibility to talk with a microphone
-improved colorFX (chrome FX need some update)
-new GUI to share your buildiings
-new easy to use events
-new camera zones ( for some rooms)
-improved light reflections
-blockBOTS (different than vehicle spawned bots, you can act they, it come with a official bot spawn, and in the place for events, it opens a GUI with anything you can make with the blockbots)
-new movie studio (you record a scene with F3, and when you open this scene in the folder, it appears a blockland director studio program, same as GTAIV movie editor, you can change the camera places, add slow motion, motion blur, sounds, and anything you want)
-new official musics
-special clothes for admins and super admins
-new and improvet jet
-new items for minigames
-grabbable bricks! (example, when fakekill, you can grab them)
-new secrets in the default maps
-new lighting reflection
-motion blur (when you get high speed, it appears the motion blur)
well that is some of my ideas
